.MOTOR FAN.

Application filed May 11, 1925. Serial No. 29,321.

My invention relates to a motor fan and particularly to constructionaldetails thereof which lessen the cost of manufacture and improve theoperation and appearance. My in'iproven'ients relate chiefly to meansfor connecting the motor bracket to the base and removably retaining themotor in the bracket.

In the accompanying drawings, which illustrate my invention, Figure 1 isa side view of a complete fan; Figure 2 is a sectional view along theline 22 of Figure 1; Figure 3 is a sectional view along the line 3- 3 ofFigure 2; and Figure 4 is a side elevational view of a portion of theoscillation mechanism.

The base 1 of the fan has its top bifurcated and the semicircularportion 2 of the motor bracket 3 tits in the space between these ends,being pivoted to the base by means of the hinge pin l. The screw clamp 5carried by the base and bearing upon the. lower part oi the portion 2 ofthe motor bracket serves to clamp the bracket in any desired tiltedposition with respect to the base. To the motor casing 6 is secured themotor spindle 7 extendin into an opening formed through the lowerportion of the bracket, and the spindle is provided with an integralcollar 8. The hinge pin is held in place by means of a plug 9 inthreaded engagement therewith, this plug being drilled out to form abottom bearing for the motor spindle 7 and itself being held againstlateral motion by being positioned in the lower end of the openingthrough the motor bracket.

B y the means justdescribed the hinge pin l: is securely held in placeand against lat eral play without the use of any external clamping screwand by means not visible in usual positions of the fan.

The tan may be oscillated by mechanism connecting the motor shaft withthe motor bracket This mechanism, in the particular iian shown,comprises the oscillating arm 10 connected at one end to the rotatngmember 11 driven by the tan shaft and at the other to the motor bracketby means oi the pin 12. As shown in Figure 3, the end oi the oscillatingarm 10 attached to the motor bracket is so shaped that a portion of thisarm extends over the collar 8 on the motor spindle when the arm is inits operative position and serves to prevent the separation of the motorand base when the tan is lifted by the motor or "tan guard. However,when the arm 10 is released from its connection to the member 11 itmaybe rotated on its pivot into a position in which no part of it extendsover the collar 8, and the motor spindle may be inserted or removed iromthe bracket.

The construction just described obviates the necessity of drilling andtapping a hole in the motor bracket and providing a screw to hold themotor spindle therein.

Having fully described my invention, what i claim as new and desire tosecure by Letters Patent oi the United States is:

1. A motor mounting comprising a base. a bracket member, a spindlecarried by the motor casing and seated in the bracket, a pivot pinextending through said bracket and having bearings in the base, andmeans for retaining the pivot pin against lateral motion with respect tothe bracket and base, said means comprising a. plug fitting into anopening in the bracket and engaging with the pivot pin, said plug beingadapted to also form a bearing for the lower end oil the motor spindle.

2. in an oscillating fan, the combination ot a mounting bracket, a motorspindle rotative therein and provided with a retaining shoulder, and anoscillation arm connecting the motor to the bracket, said arm having aprojection adapted to cooperate with said shoulder to retain the spindlein the bracket.

3. In an oscillating fan, the combination of a mounting bracket, a motorspindle rotative therein and provided with a retaining shoulder, and anoscillation arm pivoted to the bracket and having a portion eX- tendingover said retaining shoulder in assembled relation of the parts but outof engageme-nt with said shoulder when the arm is rotated on its pivotto a non-operative position.

In testimony whereof, I have hereunto set my hand this the 5th day ofMay, 1925.
